2C07 Fabrication of Polymer Periodic Structures by Means of Holography and Their Optical Response

Abstract

Periodic structures containing azobenzene moieties were fabricated by photopolymerization with three interfered beams of an Ar^+ laser at 514.5nm. After rinsing to remove unreacted monomers, an opalescent film was obtained. A two-dimensional hexagonal polymeric structure with a 3-μm period was observed by scanning electron microscopy. It was also confirmed that periodic structure was constructed in macroscopic scale by observation of six 1st-order diffracted beams of a He-Ne laser at 633nm. Upon photoirradiation at 366nm, the intensity of diffracted beam from the film decreased.
